Product Details
Mahle offers these 4.030 inch oil ring expanders with a 3.0 millimeter standard tension. These are a key component when rebuilding an engine, specifically for the oil control ring assembly on a piston. They work to keep the oil control ring properly seated and provide the necessary tension to scrape excess oil from the cylinder wall.
When you're rebuilding an engine, getting the right piston ring components is critical for proper sealing and oil control. These Mahle expanders are well-built and designed to fit pistons requiring a 4.030 inch bore size and a 3.0 millimeter oil ring width. Using the correct expander ensures the oil ring functions as intended, preventing excessive oil consumption and maintaining good compression.
This set is for standard tension applications. Always refer to your engine's specific service manual for the correct ring configuration and tension requirements during your rebuild.
